Dear Ms. McCarthy:
This is in response to your September 15, 2000 letter regarding the general requirements in § 173.27(c) for hazardous materials offered for transportation by aircraft under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you state that thousands of your hazardous materials suppliers provide no information on their hazardous material product’s vapor pressures. You asked for information on how to convert a product’s vapor pressure at 20 C to its corresponding vapor pressure at 50-55 C or for us to provide a conversion chart for this purpose.
We do not have this information available because of variations in concentrations and properties of hazardous materials. The best source for obtaining this information is from the product manufacturers. As you state, if you are unable to determine or obtain information on the vapor pressures for the hazardous material products, then they must be packaged in accordance with 173.27(c)(3).
Please contact us if we can be of further assistance.
Sincerely,
Hattie L. Mitchell, Chief
